No, it's not. FUD would be "a strategic attempt to influence public
opinion by disseminating negative (and vague) information."
I am not trying to influence public opinion, I'm reporting existing
public opinion. The consensus opinion of the sysadmins I trust most
highly is that ReiserFS is still relatively experimental and has not
yet earned their trust---several of them have been bitten by ReiserFS
bugs on their development machines (read: data loss due to
unrecoverable filesystem corruption). That said, their problems were
several years ago. Unfortunately, in the world of filesystem
reliability, trust comes slowly once lost (check out how recently
ReiserFS has been fixing quota-related problems, including ACL
In any case, I have no strategic purpose here. I have no interest or
stake in any filesystem taking over the world. If ReiserFS is
extremely stable and extremely reliable, then that's awesome, but it
does have a bit of a reputation problem. Denying that it has a
negative reputation, or claiming that anyone who describes its
reputation is spreading FUD, is not only pointless but also counter
productive. If you want to say "well, that may be what you've heard,
but I've used ReiserFS on several large, heavily-used,
mission-critical systems for several years and have not had any
problems", then that would be a useful and important statement. You'd
even be helping ReiserFS's reputation. But by having such a knee-jerk
reaction to the fact that it's got a negative reputation, you're
making the filesystem seem like it's used largely by proselytizers and
zealots---which is not a good way to build ReiserFS's reputation.

Of course - any filesystem can loose data in bad situations (such as
power loss, bad disks, etc.). Ext3 is certainly not perfect for all
situations. For example, it's a bad idea on flash media because it
keeps its journal file in a fixed spot on the drive, which can wear
out that part of a flash drive quickly. The real question is: what are
the reputations of those filesystems, and why? Ext2/3 have been around
for a very long time, and are extremely well-tested by virtue of their
popularity, and as such tend to be more trusted for mission-critical
systems (unless there's a reason they shouldn't be used).

Excellent! What kind of systems are we talking about? How heavily
loaded? Did you use it with LVM? Did you ever have to use the recovery
tools? How well did they work?
The next best thing to solving a problem is finding some humor in it.
